Hollins, I can empathise with your feelings in respect of the Nat West Llandudno. Mrs B needs to go in on a regular basis, the 'automatic' machines only work properly on occasion and the queue to be served at those silly lecterns are ridicules. The last time we were in, a staff member was typing away at a computer in that desk area on the left, I was able to see and read everything that she typed - so much for banking confidentiality!
Just prior to Christmas, Mrs B complained to the 'wandering assistant' that hangs around the machines about the service; the assistant rolled her eyes with an exasperated face when she thought Mrs B wasn't looking. I, however, was standing a few feet away (the assistant obviously did not think that we were together) and did see and I asked the assistant if she thought that her conduct was acceptable. She just went red and walked off.
